| Abstract: | In this paper we investigated cesium Faraday filter at 852 nm in the relatively weak and strong magnetic field theoretically and experimentally. With a cesium cell of 0.02 m in length in an axial magnetic field of 0.06 T, the line-center operation has been achieved. The calculated peak transmission has reached 98.6% with a FWHM bandwidth of only 3.9 GHz, the measured FWHM bandwidth of the filter is 3.29 GHz, which is general agreement with the theoretical result. |
